About Kernel codes

Hi all,
 I am always stuck with the declaration or ports in kernel code...


&du{
-----------------
------------------ bla bla....


ports {
        port@1 {
            endpoint {
                remote-endpoint = <&adv7123_in>;
            };
        };
    };};

In my knowledge I understand that here display unit has one  port(port1) which is for
vga encoder IC input signal..is it?and I am eager to know where these ports are defined in tree(In case of Koelsche,Alt,Lager etc) and am I able to change the port number..I mean,can I give above as port@0 instead of port@xxxxxx  also how can I add another ports here??

Hopping for your comments




 
Best Regards
